Schema design
A schema is a graphical data dictionary that contains metadata definitions of the structure of a document to generate test data. Schema provides visual cues for understanding the structure and complete definition of an object.

- Files
  You add a file to a project to use it as input in the project. You can upload a file from your local file system to a project from the Files tab to generate test data. Alternatively, you can upload it when you define an action.
- Connections
  A connection defines the properties that are required to connect to an external resource. An action uses a connection to provide source data to a project or write data from a source to a target. Multiple actions can use the same connection. You can define both connections and actions at the project level.

  A schema is a graphical data dictionary that contains metadata definitions of the structure of a document to generate test data. Schema provides visual cues for understanding the structure and complete definition of an object.
  - Introduction to schema design
    Use the Schemas tab to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.
  - Type properties
    The properties of a type define the characteristics of the data objects of that type.
  - Item restrictions
    Item restrictions are an optional feature you can use to specify valid or invalid data objects for an item type. Item restrictions are grouped into three categories: Value, Character, and Range.
  - Components
  - Partitioning
  - Type inheritance
  - Schema analyzer
  - Distinguishable objects

      - VALIDATE
        The VALIDATE function validates the XML input by using the XMLLIB library.
      - VALIDATEEX
        The VALIDATEEX function validates the XML input, and logs the function processing in the directory where the map runs by using the XMLLIB library.
      - XVALIDATE
        The XVALIDATE function validates the XML input.
      - XPATH functions
      - XPATHEX
        The XPATHEX function queries the XML input by using the XMLLIB library, and logs function processing in the directory where the map runs.
      - XSLT functions
      - XSLTEX
        The XSLTEX function applies an XSLT transformation to the XML input, and logs the function processing in the directory where the map runs by using the XMLLIB library.
    - Custom functions
    - Date and time format strings
    - Number format strings
    - RUN function return codes
    - Character set codes for CPACKAGE, CSERIESTOTEXT, and CTEXT

XML functions

There are several XML functions that you can call from component rules and map rules to process input XML data. They fall under two different categories. The XML functions in one category are called through the XMLLIB library. They are the XPATH (used with XMLLIB), VALIDATEEX, VALIDATE, XPATHEX, XSLT (used with XMLLIB), and XSLTEX functions. The XML functions in the other category are called directly, without using the XMLLIB library. They are the XPATH, XVALIDATE, and XSLT functions.
